Embodiment Construction

[0037] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0038] The core idea of ​​the present invention is to provide a new sensor network based on the design of PRESTO and TSAR, that is, at the Proxy agent layer, to establish a time series prediction model based on the user's historical query records, and use the prediction model to infer future user data Requirements, and obtain relevant sensing data from the Sensor sensor layer through the Model-Pull pull strategy to reduce the network burden and energy consumption caused by non-user target data reading.

[0039] figure 2 is a functional block diagram of a proxy node according to an embodiment of the present invention, the proxy node is applied in a sensor network, and the sensor network includes a sensor layer composed of multiple sensor domains, a proxy layer composed of proxy nodes in each sensor domain, and a proxy ...

Abstract

The invention relates to an agent node which can be applied to a sensor network. The sensor network comprises a plurality of sensor domains consisting of sensor nodes, at least one agent node arranged for each sensor domain and an application terminal. The agent node comprises a prediction engine module and a target data pulling module, wherein a solicited message of a user target data ID (identity) is received by the prediction engine module, and a predictive value is calculated by the prediction engine module according to the current state of the solicited message of the user target data ID and the history inquiring state of the user target data ID; the predictive value is received by the target data pulling module, and when the predictive value exceeds a decision threshold value, an order is sent to the sensor node corresponding to the user target data ID and the sensor node is controlled to report the perception data which is saved by a sensor. According to the invention, the corresponding perception data is read from a sensor layer according to the user target data ID, and extra energy consumption and network load caused by distributing data beside a user target can be reduced.

Description

technical field [0001] The invention relates to the field of wireless sensing, in particular to a proxy node, a sensor network using the proxy node and a method for acquiring sensor network data based on the proxy node. Background technique [0002] Wireless sensor network (wireless sensor network, WSN) collects various variable data in the area in real time through the sensor nodes deployed in the monitoring area, and organizes and manages these data in an effective manner. Users can obtain the data they are interested in anytime and anywhere. It has very broad application prospects. Existing sensor network data management is mainly divided into two ways: data management based on flat network architecture and data management based on layered network architecture. [0003] Data management based on flat network architecture belongs to the traditional sensor network data management method. The limited resources of sensor nodes are difficult to meet the diverse data needs of ...
